Patent GB-676968-A (GB)
Title: Improvements in circuits for cathode-ray tubes
IPC: H04J3/04
Filed: 1949-03-11
Abstract: 676,968. Cathode-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 11, 1949 [March 16, 1948], No. 6739/49. Class 39 (i). [Also in Group XL (b)] In a cathode-ray tube in which the beam is deflected over a group of targets 5, 6, 7, 8, Fig. 1, an auxiliary electrode 9 is connected by a feed-back path including condenser 16 to the deflecting plate 3, so that the angular speed of deflection of the beam during the time it strikes electrode 9 is different from the angular speed while it is striking electrodes 5, 6, 7, 8. The normal deflecting voltage is supplied by saw-tooth generator 14 via resistance 13, and deflector plate 3 is earthed via resistance 11 and battery 12. A condenser 16a, which may be variable, is connected in parallel with the resistance 11. The beam initially rests on target 5 and is deflected to the right as the saw-tooth voltage increases linearly. When the beam strikes electrode 9, the voltage drop across resistance 10 is transmitted to deflecting plate 3 so that the angular speed of deflection is increased. The arrangement may be a multiplex distributer, the time the beam takes in passing between the target electrodes 5, 6, 7, 8, thus being reduced. The variation of the resultant deflecting voltage with time depends on the time constant of the circuit comprising deflecting system 3, 4, condensers 16, 16a, and resistance 11. In an alternative method of operation, the generator 14 supplies a positive voltage pulse so that the beam is moved over to target 8. The voltage then decreases exponentially and the beam in its return path moves more slowly each time it strikes electrode 9. Compared with its angular velocity over targets 8, 7, 6, 5. In a modified construction, Fig. 3 (not shown), the additional target electrode is apertured and is arranged in front of the group of targets. If the feed-back path is connected to deflecting electrode 4 instead of to electrode 3, the beam will move more slowly when it strikes electrode 9 and faster over electrodes 5, 6, 7, 8, and this is also true in the arrangement of Fig. 3. A similar result is achieved by making the additional target electrode secondary emissive.

Title: Circuit arrangement for reproducing information at an output  thereof at an instantaneous rate which is different from its  instantaneous rate at an input thereof

Filed: 1973-02-12
Abstract: 1411859 Audio reproduction PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Feb 1973 [15 Feb 1972 7 April 1972] 6807/73 Heading H4R In a circuit arrangement for producing output signals at a different rate from the input (e.g. for playing back recordings at a speed different from the recording speed), the input signals at 3 are read-in alternately to shift registers 1, 2 via electronic switch S1 at a first rate controlled by clock pulse source f1 and are read-out via electronic switch S2 in phase opposition to S1 at a second rate controlled by clock pulse source f2, the clock sources being connected to the registers through a third, electronic changeover switch S3, S4 synchronized with S1, S2, and register outputs being coupled to their inputs via further electronic switches S5, S6. These latter switches recirculate the stored information to fill-in the gaps produced when read-out from the registers is faster than read-in. Additional or alternative feedback switches S<1>5, S<1>6 may be inserted at selected register output positions to prevent repetition of, e.g. plosives at the beginning of syllables. The electronic switches are MOS transistors possibly integrated with bucketbrigade shift registers and are controlled by unit 5 itself synchronized, e.g. by frequency division from the sources f1, f2. Transistion between register outputs can be smoothed by arranging for the switching of S2' S5 and S6 to be gradual so that during changeover the outputs of both registers read-out together at the same rate f1 or f2. In a modification to improve transition (Fig. 4, not shown) the synchronizing unit 5 for the electronic switches is triggered when both registers are at the same level and are changing in the same direction (i.e. are "in phase") by comparing (13, 23) the last two elements in the registers to produce + ve or - ve outputs which, on coincidence, open a gate (14) to operate a flip-flop (15) triggering unit (5). The changeover switch S3' S4 may be ganged to a switch controlling playback speed of a tape drive motor.
